In the week leading up to the worlds a mate of mine rang me and said that he wanted to through my name to a guy by the name of Tim Perkins who is the general manager of a company called Health Management group http://www.healthmg.com.au/. Grant has be using a product of there called a Power breather and I was lucly enough to get one from Tim to give it ago myself, Grant told me they are basically dumbbells for your lungs.
From what i have read and been told they don't increase your lungs capacity but they increase the efficiency of your lungs instead. In a nutshell the exercise your lungs. It's about 4-6 weels before you notice any real change in your breathing and studies have shown that there a gain of about 3-4% in your performance which sounds like stuff all but when you add that up over 24hrs of riding even 1% difference is alot.
Firstly you start on a build up phase of 30 breaths twice a day for 4-6 weeks then you go onto a maintenance phase.
I have not had alot time to use it but I will keep you posted on my progess. If your interested give me and email or you can get in contact with the boys fro Action Cycles in Chermside.
